User Reviews
My new obsession.
It's amazing this game isn't talked about more online by Valve fans! The similarities to Half-Life are very nostalgic, with reused audio and visual assets from the game—including Xen enemies like the Gonarch. The gunplay is very fun, and the soundtrack is brilliant. Alien Swarm has excellent story-telling and lore. I am a sucker for collecting every item I find, which is hugely addictive and offers a high level of high replay value.
[b]Would highly recommend.
this game is so bad i would rather rip my eyes out then play again. 5 stars!
Very good
